Claire Gerber wants to buy 700 shares of Google, which is selling in the market for $534.26 a share. Rather than liquidate all her savings, she decides to borrow through her broker at 5 percent a year. Assume that the margin requirement on common stock is 50%. If the stock rises to $625 a share over the next year, calculate the dollar profit and percentage return that Claire would earn if she makes the investment with 50% margin. Contrast these figures to what she'd make if she uses no margin.
